Computed tomography
Computed tomography (CT), originally known as computed axial tomography (CAT or CT scan) and body section roentgenography, is a
medical imaging method employing
tomography where
digital geometry processing is used to generate a
three-dimensional image of the internals of an object from a large series of two-dimensional
X-ray images taken around a single axis of rotation. The word "tomography" is derived from the
Greek tomos (slice) and graphein (to write). CT produces a volume of data which can be manipulated, through a process known as windowing, in order to demonstrate various structures based on their ability to block the
X-ray beam. Although historically (see below) the images generated were in the axial or transverse plane ( to the long axis of the body), modern scanners allow this volume of data to be reformatted in various planes or even as volumetric (3D) representations of structures.

Tomografia komputerowa
Tomografia komputerowa, TK (
ang. Computed Tomography - CT) jest rodzajem
tomografii rentgenowskiej, metodą diagnostyczną pozwalającą na uzyskanie obrazów tomograficznych (przekrojów) badanego obiektu. Wykorzystuje ona złożenie projekcji obiektu wykonanych z różnych kierunków do utworzenia obrazów przekrojowych (2D) i przestrzennych (3D). Urządzenie do TK nazywamy tomografem, a uzyskany obraz tomogramem. Tomografia komputerowa jest szeroko wykorzystywana w medycynie i technice.

Tomografia computerizzata
In
radiologia la tomografia computerizzata, indicata con l'
acronimo TC o CT (dall'
inglese computed tomography), è una metodica diagnostica per immagini, che sfrutta radiazioni ionizzanti (
raggi X) e consente di riprodurre sezioni (tomografia) corporee del paziente ed elaborazioni tridimensionali. Per la produzione delle immagini è necessario l'intervento di un elaboratore di dati (computerizzata).
